Abstract
The thermal performance of a regenerative active solar distillation system working under the thermosyphon mode of operation has been studied for a Delhi climatic condition. The effects of climatic and system design parameters have been incorporated in the basic energy balance equations for each component of the system. The studies have been made in terms of overall thermal efficiency as well as hourly yield from the system. On the basis of the numerical results, it is concluded that (i) there is a significant improvement in overall performance due to water flow over the glass cover and (ii) the hot water available due to the regenerative effect does not enhance the output.
